JSON Decode Online PHP

In this tutorial we will show you the solution of json decode online PHP, here we needs to use ‘json_decode()’ method for decode json data’s. The json_decode() function is an inbuilt function in PHP which is used to decode a JSON string.

It converts a JSON encoded string into a PHP variable and we passing that converted value to var_dump() method for displays it structure information (type and value).

Step by step guide on JSON decode online PHP :-

Here we defined variable $jsonobj for store json data, as we know it contains key, value pairs we can define as per our wish.

We specified json data is ‘{"Peter":35,"Ben":37,"Joe":43}’ then using json_decode method we are going to converting this as php variable then when conversion process gets completed at that time it will passed to var_dump method because which is help us to displays it structure clearly.

<?php
$jsonobj = '{"Peter":35,"Ben":37,"Joe":43}';
var_dump(json_decode($jsonobj));
?>
  1. A php script can be placed anywhere in the document. A php script starts with <?php and end with ?>.
  2. The default file extension for php files is “.php” and php statements end with ‘;’ semicolon.
  3. Here we needs to define json data for the decoding process so we are declared variable ‘$jsonobj’ for initialize some json data of key, value pairs (i.e) ‘{"Peter":35,"Ben":37,"Joe":43}’.
  4. If you’re need any other json data means we can modify it too easily it won’t affect result because here we are decoding json data that’s all whatever json data it can accept.
  5. Then first we need to pass them to the json_decode() method it will convert any json data string to php variable.
  6. The json_decode() method can return a value encoded in JSON in appropriate PHP type. The values true, false and null is returned. The NULL is returned when JSON can’t be decoded or if the encoded data is deeper than the recursion limit.
  7. The json_encode() also same like this, it will encodes a value to JSON format later we will see this with example.
  8. That json_decode return type is boolean so we are pass that result of converted variable to var_dump method for gets it structure (type and value) information about one or more variables then displays on webpage.
  9. Usually in this method, arrays and objects are explored recursively with values indented to show structure. All public, private and protected properties of objects will be returned in the output.

Conclusion :-

In conclusion now we are able to know how to decode json string using php.

When work with php we need to create and process php files at server location and then we need to start the server before execute the program.

When we executing this program on browser it will prints result ‘ object (stdClass) # 1 (3) { ["Peter"]=> int (35) ["Ben"]=> int (37) ["Joe"]=> int (43) } ’.

We can also modify this like we seen above and try to explore with some other values it will help you to know more.

I hope this tutorial on json decode online PHP helps you and the steps and method mentioned above are easy to follow and implement.
